Robert's post is a good primer for anyone who is interested in joining the Scottish Rite and is encountering this subject for the first time. It is not a critique of either jurisdiction - it is merely the observations of a Brother who has experienced degrees in both.
Give it a look HERE.
Many Masons often ask why there is so much difference between the philosophy of the two jurisdictions in the US regarding their rituals. It can best be summarized by the late Melvin Maynard Johnson, the NMJ's former Sovereign Grand Commander, in his Allocution from 1943:
“If the time ever comes when the Scottish Rite determines to remain static, when its philosophy may not be adjusted to the needs of a chang- ing world, then is the time for its obsequies. Until then, its leaders should never abandon study of the philosophy of its ritualistic teachings that, by recast and revision, it may keep in the van of advancing civilization.”
"It is of passing interest that in 1960 the Supreme Councils of the Northern and Southern Jurisdictions of the United States agreed to joint meetings of their respective Committees on Rituals for the purpose of promoting greater uniformity in degree work. Before any meetings were held, however, the Southern Jurisdiction withdrew from the venture on the grounds that its ritual, written by Albert Pike, already “was as perfect as humanly possible.” Hence, there was no reason to discuss change, notwithstanding that Pike himself had been the greatest innovator of Masonic ritual and, over a period of 30 years to 1884, had revised the initial versions of his own rituals. Perfect or not, the reality was that Valleys across the Southern Jurisdiction routinely were abridging and adapting the Pike ritual to suit their individual situations. Perhaps it was inevitable that, starting in 1985, the Southern Jurisdiction began to soften its stance by undertaking to modify and simplify, i.e., abridge, the Pike ritual. This process culminated in 2000 with issuance of The Revised Standard Pike Ritual."Illus. Bro. Trexler's work is the only relatively up to date document that even discusses the NMJ degrees, while the SJ has published a stream of books over the years to explain or explore the rituals Pike wrote between 1860-87. Trexler's book does not disclose any of the actual rituals, signs, symbols, etc. It is merely a history of the changes the NMJ degrees have undergone over the last century or more. But it is of interest to those who have wondered about the subject. To my knowledge, it exists only online, and then as an archived file on the Wayback Machine archive.
A new book has been written by a NMJ Mason, and it covers the newest versions of the NMJ degrees, explains each one, tells its history, the background of each story told in the ritual, and also adds a brief description of its SJ counterpart just for good measure. This promises to be a boon to NMJ Masons who have been begging for something similar for years, and it frankly should have been published officially by the Supreme Council. It is due to be released later this year by Starr Publishing.
